// Omnibox Actions are additional actions associated with matches. They appear
// in the suggestion button row and are not matches themselves.
//
// Omnibox Pedals are a type of Omnibox Action.
//
// Actions are ref-counted to support a flexible ownership model.
//  - Some actions are ephemeral and specific to the match, and should be
//    destroyed when the match is destroyed, so matches have the only reference.
//  - Some actions (like Pedals) are fixed and expensive to copy, so matches
//    should merely hold one of the references to the action.
// Note: `RefCountedThreadSafe` is used instead of `RefCounted` because
//  AutocompleteMatch instances are passed across thread boundaries to
//  different sequences and they contain `scoped_refptr<OmniboxAction>`.
